[0002] A children's seat is a seat designed for children, usually relatively small and brightly colored, mostly made of plastic. Plastic children's seats are usually injection molded. Due to factors such as the precision of the mold, the fit clearance, and the injection pressure, burrs and flash will remain on the finished plastic children's seats. These burrs and flash need to be properly processed before leaving the factory, otherwise there is a risk of injuring children. Currently, the cleaning of burrs and flash on the surface of plastic children's seats is mostly completed by a dry ice cleaning machine. When dry ice is ejected, heat exchange occurs with the burrs and flash, which can increase the brittleness of the burrs and flash, and then they can be easily crushed by the airflow. Especially when cleaning the flash and burrs in holes and grooves, it is more convenient and effective.

[0003] In the actual production of plastic children's seats, some seats only have burrs or flash in a single area on the surface. When the existing dry ice cleaning machine is used, it cannot perform fixed-point cleaning, and relevant personnel need to hold the spray gun at all times, resulting in a large physical consumption and inconvenient and inflexible use.

[0004] Therefore, it is necessary to provide a new surface treatment device for plastic children's seats to solve the above technical problems. Content of the Utility Model

The structure of the dry ice cleaning machine adopts the conventional design of the prior art, which mainly includes a central control box 2, a flexible connecting pipe 3 and a spray gun 4. One end of the flexible connecting pipe 3 is fixedly connected to the dry ice outlet of the central control box 2, and the other end is fixedly connected to the barrel of the spray gun 4. A slide rail 5 is fixedly installed at the bottom of the platform 1. An L-shaped movable seat 6 is slidably sleeved on the slide rail 5. A rectangular slide groove is provided in the L-shaped movable seat 6. A lifting seat 7 is slidably installed in the rectangular slide groove. The top of the lifting seat 7 extends to the top of the L-shaped movable seat 6. A connecting block 8 is fixedly installed on the outer wall of one side of the L-shaped movable seat 6. An adjusting screw 9 is passed through and threadedly installed on the connecting block 8. The top of the adjusting screw 9 is rotatably connected to the lifting seat 7. Specifically, a shaft seat is fixedly installed on the lifting seat 7, and the top end of the adjusting screw rod 9 is rotatably connected to the shaft seat. Two support blocks 10 are fixedly installed on the top of the lifting seat 7, and a rotating shaft 11 is penetrated and rotatably installed on the two support blocks 10. The ends of the two rotating shafts 11 close to each other are fixedly installed with the same rotatable base 12, and an L-shaped fixing frame 13 is fixedly installed on the top of the rotatable base 12. An adjusting screw 15 is penetrated and threadedly installed on the L-shaped fixing frame 13, and a pressing block 14 is slidably installed on the inner wall of one side of the L-shaped fixing frame 13. When in use, the barrel of the spray gun 4 is placed between the pressing block 14 and the rotatable base 12, and the bottom end of the adjusting screw 15 is rotatably connected to the pressing block 14. The adjusting screw 15 is rotated forward to make the pressing block 14 descend to press the spray gun 4 tightly, so that the spray gun 4 can be fixed.

[0021] In this embodiment, in order to limit the child seat, a seat limiting mold base 19 is fixedly installed on the top of the platform 1. The seat limiting mold base 19 is provided with seat leg limiting holes of various specifications, and each specification has four seat leg limiting holes. When in use, the four legs of the child seat to be processed are inserted into the corresponding four seat leg limiting holes, so that the child seat can be limited to avoid arbitrary movement.

[0022] In this embodiment, in order to fix the L-shaped movable seat 6 , a first abutment screw 16 is passed through and threadedly installed on the L-shaped movable seat 6 , and one end of the first abutment screw 16 abuts against the platform 1 .

[0023] In this embodiment, in order to fix the rotatable base 12, a disc 17 is fixedly installed on one end of one of the rotating shafts 11 away from the rotatable base 12, and a second interference screw 18 passes through and is threadedly installed on the disc 17, and one end of the second interference screw 18 interferes with the corresponding support block 10.

[0024] In this embodiment, in order to increase the reliability of fixing the spray gun 4, arc-shaped through grooves are provided on the top of the rotatable base 12 and the bottom of the pressing block 14, and rubber pads are fixedly installed in the two arc-shaped through grooves.

[0025] The working principle of the surface treatment equipment for plastic child seats provided by the utility model is as follows:

[0026] When there are burrs and flashes in only a single area on the surface of the child seat, fix the spray gun 4 between the rotatable base 12 and the pressing block 14, and then adjust the position and spray angle of the spray gun 4 to aim at the burr and flash area. The specific operation is: first place the child seat in the four corresponding seat leg limit holes on the seat limit mold base 19, and then place the barrel of the spray gun 4 into the arc groove on the rotatable base 12, and then rotate the adjusting screw 15 clockwise. The adjusting screw 15 will move downward during the clockwise rotation, thereby driving the pressing block 14 to move downward. Finally, the pressing block 14 cooperates with the rotatable base 12 to clamp the barrel, so that the spray gun 4 can be fixed;

[0027] After completing the fixing work of the spray gun 4, rotate the first abutting screw 16 counterclockwise to separate it from the platform 1, and then the L-shaped moving seat 6 can be moved left or right. When the left and right positions of the L-shaped moving seat 6 are adjusted appropriately, rotate the first abutting screw 16 clockwise to make the first abutting screw 16 abut tightly against the platform 1. Then, rotate the second abutting screw 18 counterclockwise to separate it from the corresponding support block 10. In this way, the rotatable base 12 loses its fixation, and then the rotatable base 12 can be rotated. During the rotation of the rotatable base 12, the spray gun 4 will be driven to rotate. When the air outlet of the spray gun 4 is aligned with the burrs and flash on the surface of the child seat, rotate the second abutting screw 18 clockwise to make it abut tightly against the corresponding support block 10 again. In this way, the orientation of the muzzle of the spray gun 4 can be fixed. In addition, if the height position of the spray gun 4 is not appropriate and the muzzle cannot be aligned with the burrs and flash, the height of the spray gun 4 can be adjusted by rotating the adjusting screw rod 9. During the process of rotating the adjusting screw rod 9 forward or backward, the adjusting screw rod 9 will move upward or downward, and the adjusting screw rod 9 drives the lifting seat 7 to move correspondingly, so that the height position of the spray gun 4 can be adjusted appropriately. Combining with the adjustment of the angle and left and right positions of the spray gun 4 in the above text, finally, the muzzle of the spray gun 4 can be aligned with the burrs and flash on the surface of the child seat. After the spray gun 4 is turned on, the dry ice in the central control chassis 2 will be sprayed towards the burrs and flash along with the high-pressure air flow. After the dry ice is sprayed out, it will undergo heat exchange with the burrs and flash and vaporize, and the brittleness of the burrs and flash will increase, and finally they will be broken by the impact of the air flow. When subsequent same-type child seats are subjected to surface cleaning, only need to place the child chair in the corresponding four seat leg limit holes on the seat limit die base 19, and then turn on the spray gun 4 for spraying and flushing;

[0028] When there are burrs and flash on multiple areas of the surface of the child seat, the adjusting screw 15 can be rotated counterclockwise to release the fixation of the spray gun 4, and then the relevant personnel can hold the spray gun 4 for spraying and flushing.

[0029] Compared with the related technology, the plastic child seat surface treatment equipment provided by the present utility model has the following beneficial effects:

[0030] The utility model provides a surface treatment device for plastic children's seats. Through the settings of components such as a slide rail 5, an L-shaped moving seat 6, a lifting seat 7, a connecting block 8, an adjusting lead screw 9, a rotatable base 12, an L-shaped fixing frame 13, a pressing block 14, a seat limiting die base 19, etc., when processing children's seats with burrs and flash on multiple surface areas, relevant personnel can hold a spray gun to perform spraying and flushing. When processing children's seats with burrs and flash on only a single surface area, the spray gun of the dry ice cleaning machine can be fixed, and then the left and right position, height position and tilt angle of the spray gun can be adjusted as needed so that the muzzle of the spray gun is aligned with the area with burrs and flash. During cleaning, relevant personnel only need to manually turn on the spray gun 4 to achieve fixed-point cleaning, avoiding holding the spray gun 4 for a long time, and having the advantages of convenience, labor saving and flexible use.
